To all whom itmay com-em :1 1

Be it known that I, Hansen: B. Nrcnons, a citizen of the United States, residing at. Belle Island, South Norwalk, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements'in Washers for Photographic Films and Prints,

of which the follow ng is a specification,

reference being had to the accompanying drawings, which form a part hereof.v

This invention relates to washers for photographic films and prints.

The invention seeks to provide an eflicient" and inexpensive device adapted to create a whirlof water within a suitable vessel for washing photographic films and prints and thereby removing traces of the acid which may have adhered thereto after their previous treatment.

Referring now to the accompanying drawings forming part oi this specification and in which like reference numerals designate corresponding parts in the several figures,

, and which show. the invention in its preferred form, Figure 1 is a side elevation of the washer, the same being shown in its operative relation with reference to a washing pan. Fi 2 is a side elevation showing the nozzle oi the washer. Fig. 3 is an edge view of the nozzle looking toward the left of Fig. 2. I

Referring now to the various details as shown in t. a pan or other suitable vessel designed to contain a supply of water and within which the films and prints are' intended -.to be washed. The nozzle 2 comprises atuhular portion 3 provided with a piuraiity' of nip -pics, such as those marked 5 and 6, the

latter two oi-which' are preierabiy directed somewhat downward, ias' ishown in Fig. 7 2.. 'Removahly connectin with the tubular portion 3-is a flexible to e? adapted to he removably connected with e evates faucet '8.

Rigidly'secured to one'side 0t the'tubular portion 3 is a holdingciiphaving a fixed aw 10 and a movable spring jaw 9. This holding clip is designed and-adapted to receive and clasp between its gaws one side of the pan i, 'as shown-311 B 1, thereby holding the nozziein working; position and thus .e accompanying drawings, 1 is dispensing with the necessit of holding the nozzle .m place by hand. igidly fixed to the opposite side of the tubular portion 3 is a thin plate constituting a shield 11. The

rear margin of this shield is curved partly around the tubular portion 3 and is brazed or otherwise united to the adjacent margin of the jaw '10 of the holding clip, as shown at 12 in Figs. 2 and 3. The opposite margin of the shield 11 projects slightly beyond the. outer ends of the nipples.

Vhen the washer is in operation, the water jets emitted from the nipples impart a whirlmg motion. to the water contained within the vessel 1. The films and prints immersed in the water are moved about here and there, and generally in a circular direction, owing to the whirling action of the water within the pan and the action of the streams emitted from the nipples, thereb washing off all the acid that may have ad ered to them.

the films and prints take up the circular motion of the water in the vessel, they are prevented from catching upon the nozzle by the shield 11, thisshield hein on that side of the nozzle which faces the ody of water within the vessel.

In. the preferred form of the nozzle, 1 make the nipples of increasin length toward the outer end of the nozz c. This arrangement is more .efiective in producing and maintaining the proper motion of the ,water in the pan.

While i have shown the invention in its preferred form, it is to be understood that the particular form may be variously 'modified without departing from the spirit of the invention. I

iihat '5 claim is:

l. in a washer for photographic films and pri'nts,a nozzle comprising a tubular portion having a plurality of nipples of increasing length toward the outer end of the nozzle, and a holding clip for attaching the nozzle to the "Wall oi" a suitable washing vessel and thereby holding the'nozzle in working po sition.

2. in a washer for photographic films and prints, a nozzle comprising a tubular portion havin a plurality of nipples and a fixed shiel to'prevent the filmsand prints under-treatment from catehing on the nozzle.

3.111 a Washer for photographic films and prints, a nozzle comprising" a tubular portion provided with means for emitting jets of water, a fixed shield to prevent the films and prints under treatment from catching on the nozzle and a holdin clip for attaching the nozzle to the wall of a. suitable washwep'oe 7 ing vessel and thereby holding the nozzle 10 working position.

This specification si ed and witnessed this'3lst day of July, A. D, 1914 HERBERT B. NICHOLS.
